Green Valley Creek is a major tributary in the lower Russian River Watershed, and is part of the Guerneville HSA. It is a third order stream containing critical habitat for steelhead trout, remnant populations of coho salmon, and in its lower reaches Chinook salmon.
The Recovery Strategy for California Coho Salmon (CDFG, 2004) identified the Guerneville HSA as having the highest ranking (level 5) for restoration and management potential in the CCC Coho ESU.
There are approximately 18.7 miles of blue line stream in the Green Valley Creek Watershed, including Purrington Creek, which contributes important summer flow to the stream system. Green Valley Creek is one of only five remaining streams in the Russian River drainage where wild juvenile coho are known to exist.

California Department of Fish and Game (DFG) stream inventory reports from the last decade assessed spawning and rearing habitat in Green Valley Creek and its tributary Purrington Creek. Higher quality spawning and rearing habitat were identified in two upper reaches of Green Valley Creek.
The highest quality salmonid habitat in the stream system is located above the confluence with Atascadero Creek and in the lower portion of Harrison Creek. However, according to the 1994 stream inventory report, sedimentation in the upper portion of the watershed has the potential to seriously degrade higher quality habitat downstream. The stream habitat report for Purrington Creek found that the tributary's lower reach contained fair habitat for salmonid rearing, while its upper reach had fair habitat for both spawning and rearing.
Green Valley Creek Gauge Data
Disclaimer: The gauge data reported here are preliminary, have not been verified, and may be unreliable for reasons including, but not limited to, instrument malfunction, undetected disruptions or interference occurring at the measurement site, or errors in interpretation. Please note that data are currently available only for water depth (not flow), temperature data has not been reviewed or calibrated, instruments may be located above the water levels in pools, and some instruments measure stage up to a certain height and will display a flat line at zero or the maximum height once that maximum measurable stage is reached.
